The Swarm Wars have been grinding on for years, and Earth has been occupied. Kyoto, a rookie pilot, enlists with the Galactic Stargate Authority to fight back—and finishes training just in time for the Manti to launch their largest offensive yet against Cydonia Base. Pushed to the far edge of the solar system, the GSA scrambles to organize its response. Kyoto will receive mission orders from the Battleship Memory, absorb criticism from the demanding Colonel Adams, and gather tactical intelligence about the Manti from the researcher Dr. Mudo—all while working toward the operation that might end the second alien swarm for good.
